I see this post is a bit old, however I just discovered this forum, and may have an answer to the games question.

Having just recntly discovered the programmable calculator I started scanning the net for different programs. The calculator I decided to try first is the Casio 7400.

It does seem to suffer from a lack of graphic oriented games, however I think text based games are plentiful.

Way back in the 80s when I had a trs-80 model 3 and a color computer, I got a book called "Basic Computer Games" or some similar title. It occured to me that most of these games were text based and would be perfect for the 7400.

I scoured the net and found a site that had the program code for classics such as "Hunt the Wumpus", "Hamurabi", "Darmouth Football", "Battlestar Galactica" and "Star Trek". There were many others, but I thought this would be a good start.

These games are text only, but those of us who remember them know how fun they really were.

The code for them is Basic, but I have them all here and think that they should be easily translated to Casios "Basic like" language.

I still have a day or 2 left that I need to continue learning Casios language.

If you understand Basic, then translating these old programs to Casio should be easy.
